Detroit Lions head coach Rod Marinelli said WR Reggie Ball (knee) suffered a knee injury. "I can't say exactly what it all is. The (doctor) I know came in this morning to look at it, but he's out," Marinelli said. "He could be out - done."

Nicholas J. Cotsonika, of the Detroit Free Press, reports undrafted free-agent QB Reggie Ball (Georgia Tech) is trying out with the Detroit Lions as a wide receiver. "A lot of people want to see me at wide receiver instead of quarterback, so you know, I'm just going to take it and run with it," Ball said.

Gil Brandt, of NFL.com, reports Georgia Tech QB/WR Reggie Ball measured a weight of 197 pounds at his Pro Day. He ran the 40-yard dash in 4.69 seconds and 4.67 seconds and the short shuttle in 4.44 seconds. He measured a 32-inch vertical jump and a 9-foot-10 broad jump.
